I need of specific Theme

I am looking for a theme that looks like something shown beneath. I don’t quite know how to describe it so I made a quick sketch in Paint. Don’t consider the ratios. I am mostly looking for Theme 2 where I can put as many sections (box 1, 2…) as I want.

This is not for a blog but for a website. Do you have any recommendations? I prefer a free theme since I am still testing but don’t mind paying if it is worth it. I would appreciate some that has some kind of support so I can ask when in doubt. I am very new to this.

Thank you!
